ENERGY EFFICIENCY CONSIDERATIONS

PRODUCT INFORMATION

/ Lightweight cladding system./ Readilyacceptsmanyformsofdecorativefinish./ Highly durable product./ Dynamic architectural style./ Fully sealed and balanced panels.

Energyefficiencyrequirementshavebeenintroducedintothe Building Code of Australia (BCA) for both commercial and residential buildings. Thermal heat transfer into and out of the buildingenvelopewillaffecttherunningcostofthebuildingandcareful consideration of the thermal heat transfer needs to be addressed by the architects, engineers and building designers. Thermal bridging through steel framing will diminish the total R-Value; thermal conductance, of the wall. Thermal breaks arerequiredforsteelframedbuildings.Thermalbreaksshould have a minimum R-Value of 0.2.

Duracom™ panels are a compressed, autoclaved, cellulosefibrereinforcedsilica/cementpanel,speciallyformulatedandpreparedtomeettherequirementsforuse in exterior applications.

Duracom™ Facade System, utilizing BGC Fibre Cement Compressed Panels and Cold Formed Section (CFS) steel support framing, to form a strong and durable facade cladding system.

Duracom™panelsfixedtotheCFSsteelsupportframing, are ideally suited for versatile architectural facades and parapet applications in industrial, institutional, commercial and multi-storey residential buildings.

Duracom™ panels are designed for installation in a variety of patterns, including vertical, horizontal, brick-bond or diamond inclined.

Duracom™ panels are available in 9mm and 12mm thicknessesandarefinishedwithsiteappliedacrylicpaint systems.

COASTAL AREAS

The durability of galvanised fasteners used for exterior cladding in coastal or similar corrosive environments can be as low as 10 years.

For this reason BGC recommend the use of Stainless Steel fasteners within 1km of the coast or other large expanses of salt water.

DESIGN CONSIDERATIONS

Itisrecommendedthatprojectspecificfacadedesignsbeundertaken by a consultant experienced in such detailing.

The design engineer should determine the wind pressure fortheprojectandspecifythelayout,spacingandfixingof the top hats to the structure.

Thedeflectionofthesupportingstructureshouldbelimitedspan/250 for Serviceability Wind Load, or as limited by AS/NZS1170. 2:2002

In areas where there is a probability of wind loading, care should be taken in the design detailing, especially aroundallopenings,cornersandotherjunctions,to ensure the weather resistance of the total system.

Before the Duracom™ panels and the supporting substructureareinstalledandfixed,particularcareshouldbetakenthatallflashingandwaterproofingworkiscomplete,including all vapour permeable building wraps and damp proof coursing.

Inmanycases,controljointswillnotberequiredastypicalexpressedjointspermitsomedifferentialmovementoftheDuracom™ panels and the sub-framing.

It is recommended that the designer consider the need for controljointsinthefollowingcases:

/ Wherethefacadecrossesabuildingcontroljoint./ Where there is likelihood of movement in the sub-framing./ Continuous facades greater than eight (8) metres in length./ At a change in the structural substrate; eg. masonry to steel framing./ Refer to drawings on P17-19.

PANEL PREPARATIONForinsitupaintfinishapplications,Duracom™panelsaresupplied sealed with a proprietary sealer applied during manufacture for durability.

Where it is necessary to cut sheets, cutting tools should have a dust extraction system.

Cut edges must be sealed with BGC Edge Sealer or an acrylic coating to eliminate moisture absorption.

A saw blade such as BGC Durabladewith a poly crystalline diamond tip specificallydesignedtocutfibrecement sheets is recommended.

Ensure work area is well ventilated and wear an approved dust mask (AS/NZS1715 and AS/NZS1716) and safety glasses (AS/NZS1337).

It is recommended to cut the sheetsface down in order to get the bestend results.

Structural sub-frame spacing must be installed in accordance withBGCfixingspecifications.Table4providesguidanceonthemaximumspanofTopHatprofile.

The design capacities of the DuracomTM Facade System are in limit state format and are based on AS/NZS1170.2-2002 Wind Actions.

The Top Hat capacities have been calculated in accordance with AS/NZS4600 – cold form steel structures.

FIGURE 3 FIXING SEAL TO TOP HAT

Set out, pre-drill and countersink the holes in the panels to be mounted, as set out in the table hereunder.Screw holes must be pre-drilled, allowing 1mm clearance over diameter of screw.Holes must be drilled using a masonry drill bit.Do not use an impact drill.Where screws are to be countersunk, depth must be controlled by gauge to restrict head depth to 3mm maximum.

Refer to Table 5 for Maximum Spacing of Panel Fasteners.

The exterior surface of Duracom™ must be coated withanappropriatefinish.Thesealedbackfaceisnotsuitablefor exposure to ultra violet light and therefore should not be exposed other than for short periods ie during installation. The sealed front face should be painted within three (3) months of initial exposure to ultra violet light.
